---------------------------------------------------------------
The drilldown in this example is done in the traditional SAS/Graph way ...
First, a character variable is created, containing the html tags for
the drilldown (href=) and the text charttip/rollover-text (title=)
as follows ...
length htmlvar $500;
htmlvar=
'title='||quote(
'State: '|| trim(left(st)) ||'0D'x||
'Population: '|| trim(left(put(population,comma12.0))))||
' href="http://www.state.'||trim(left(lowcase(st)))||'.us"';
Then that variable is specified using the "html_legend=" option in the
SAS/Graph "proc gchart" as follows (this is very similar to using the
html= option, but this puts the drilldowns on color/pattern squares
in the legend, rather than on the bars themselves)...
proc gchart data=mydata;
hbar st / type=sum sumvar=population ascending nostats
subgroup=st
maxis=axis1 raxis=axis2
autoref cref=gray clipref
coutline=black legend=legend1
html_legend=htmlvar <-------- here!
des='' name="&name";
run;
And the output is created using ODS HTML, and "goptions device=png",
so that a png file is created containing the png, and an html file
is created containing the html charttips & drilldowns. The user will
view the html file, and it will display the png image.
